DPT Therapeutic Interventions & Techniques 3

Question 1

Which manual therapy technique is MOST appropriate to restore posterior capsule extensibility in a patient with adhesive capsulitis?

Accepted Answer

Posterior glide of the humeral head

Answer

Posterior glide mobilization of the humeral head directly stretches the posterior capsule, which commonly becomes contracted in adhesive capsulitis.

Question 2

A patient is prescribed aquatic therapy. Which property of water allows a therapist to grade resistance during exercise?

Accepted Answer

Viscosity and drag

Answer

Water viscosity creates drag that increases with movement speed, allowing progressive resistance by simply moving faster through the water.

Question 3

Which dry needling target is MOST consistent with treating a myofascial trigger point in the upper trapezius?

Accepted Answer

A taut band with a local twitch response

Answer

Myofascial trigger points are located within taut bands; eliciting a local twitch response confirms accurate needle placement within the trigger point.

Question 4

When using phonophoresis to deliver a topical anti-inflammatory, which ultrasound frequency penetrates most superficially?

Accepted Answer

3 MHz

Answer

3 MHz ultrasound is absorbed more rapidly in superficial tissues (1–2 cm depth), making it ideal for superficial phonophoresis targets.

Question 5

A therapist applies transcutaneous electrical nerve stimulation (TENS) for pain control using high-frequency, low-intensity parameters. This mode primarily activates which pain gate mechanism?

Accepted Answer

Segmental inhibition via large-diameter Aβ fibers

Answer

Conventional high-frequency TENS activates large-diameter Aβ mechanoreceptors that inhibit nociceptive transmission in the dorsal horn via gate control theory.
